Granted: 2010-08-10
Abstract: A method and apparatus for providing a network based operating system for mobile clients is disclosed. Services may be developed that can be used to support different client devices with different capabilities. The services provide output with multiple variations based on different devices, and an intermediary selects the variation best suited for the requesting device. An online software development system is provided to allow services to create, edit, test, and deploy applications at an intermediary using only a browser at the client end. Services may also be provided that can be accessed and referred to by other services, thereby facilitating the combining of different services. Services may also store and access data at an intermediary using variables and a mapping of the stored data to the variables. Data stored at the intermediary may be used to allow an end user to return to a previously accessed service.

Abstract: Air driven dental handpiece motors include a tubular housing and a rotor rotatably supported within the housing. One motor is geared down by the provision of a plurality of idler gears rotatably supported on a hub which rotates between a sun gear on the output end of the rotor and a ring gear fixed within the housing. A drive shaft connects an exposed drive gear with the hub. A bearing is provided between the drive shaft and the inner bore of skirt extending from the ring gear to reduce a number of tolerances built up between the drive shaft and the bearing.      The motor further includes a valve member rotatable through about 140° of arc to vary maximum motor speed and motor rotation direction. The valve member abuts a valve plate having a circular air inlet opening and a semicircular air outlet or exhaust opening. The valve member has an air supply opening which is an elongated arcuate slot having radiused circumferential ends. Shallow, curvilinear recesses are provided in line with circumferential outer and inner walls of the central slot at each circumferential end of the slot and provide fine, low speed adjustment capability to the valve. Deeper recesses at the center of the slot provide an effective air supply orifice diameter at least as great as the effective orifice diameter of the valve plate inlet air opening to maximize top motor speed.

Title: Bit rate reduction in audio encoders by exploiting inharmonicity effectsand auditory temporal masking
Inventor: NAJAF-ZADEH HOSSEIN
IPC: G10L25/90
Filed: 2003-08-27
Granted: 2012-02-21
Abstract: The present invention relates to a method for encoding an audio signal. In a first embodiment a model relating to temporal masking of sound provided to a human ear is provided. A temporal masking index is determined in dependence upon a received audio signal and the model using a forward and a backward masking function. Using a psychoacoustic model a masking threshold is determined in dependence upon the temporal masking index. Finally, the audio signal is encoded in dependence upon the masking threshold. The method has been implemented using the MPEG- 1 psychoacoustic model 2. Semiformal listening test showed that using the method for encoding an audio signal according to the present invention the subjective high quality of the decoded compressed sounds has been maintained while the bit rate was reduced by approximately 10%. In a second embodiment, the inharmonic structure of audio signals is modeled and incorporated into the MPEG-1 psychoacoustic model 2. In the model, the relationship between the spectral components of the input audio signal is considered and an inharmonicity index is defined and incorporated into the MPEG-1 psychoacoustic model 2. Informal listening tests have shown that the bit rate required for transparent coding of inharmonic (multi-tonal) audio material can be reduced by 10% if the modified psychoacoustic model 2 is used in the MPEG 1 Layer II encoder.

Abstract: La présente invention concerne des systèmes de communication numériques en mode rafale, dans lesquels la transmission de données est précédée par un préambule d'acquisition de porteuses et la synchronisation des horloges au moyen du principe de certitude maximale. Ce préambule est échantillonné et la série d'échantillons obtenue est traitée à l'aide d'algorithmes d'optimisation de cette invention pour produire l'estimation de synchronisation de certitude maximale. Ces algorithmes d'optimisation comportent trois parties. La première partie a trait à l'isolation de l'estimation optimale souhaitée provenant des extrêmes non optimales qui satisfont la même condition requise, et elle engendre les conditions initiales d'activation des schémas de recherche binaire. La seconde partie réalise la recherche binaire de l'estimation de synchronisation optimale qui garantit la convergence. Sur la base de la séquence itérative obtenue, la dernière partie élabore une séquence qui converge plus rapidement de manière à obtenir l'estimation de synchronisation du symbole de certitude maximale. A l'aide de l'estimation de synchronisation de symbole obtenue, l'estimation de la phase de la porteuse de certitude maximale peut être calculée explicitement et la synchronisation réalisée.

Abstract: The present invention generally relates to an apparatus for sealing a wellbore. The sealing apparatus includes an expandable tubular body having one or more sealing elements disposed thereon. In one aspect, the sealing elements include swelling and non-swelling sealing elements. Preferably, the swelling sealing elements are made of a swelling elastomer capable of swelling upon activation by an activating agent. The swelling elements may be covered with a protective layer during the run-in. When the tubular body is expanded, the protective layer breaks, thereby exposing the swelling elements to the activating agent. In turn, the swelling elements swell and contact the wellbore to form a fluid tight seal.

IPC: B01F23/10
Filed: 2004-02-27
Granted: 2008-08-26
Abstract: A thermal mixer reduces the temperature of flue gas supplied to a fabric filter. Two spray dry absorbers are operable to cool flue gas. A housing of the mixer has first and second inlet passages for gas from the absorbers, an outlet passage for gas to the fabric filter, and a mixing passage. A set of damper vanes extends in the mixing passage and has a mixing position for mixing the flue gases from the inlet passages to supply mixed gas to the outlet passage at relatively high pressure drop but lower temperature if one of the absorbers in not operating. They have a non- mixing position for passage of gases without mixing and at fow pressure drop when both absorbers are operating. The invention can also be used to improve mixing of combined gas streams initially having different chemical compositions or amounts of particle loading.
